If i post this instructable, will it be taken down? Answered

I'm planning to put "How to rapidly produce hydrogen gas (faster than electrolysis)"



11 years ago

But electrolysis is soooooo coooool! Seriously that was like the coolest thing I ever got out of a science textbook.

Sorry I ment to say "Electronics" instead of "electrons"

I dont think that it would, But just be sure to include a notice such as "I am not responsible for any mis uses or irresponsible acts." Do you have any other Instructables involving electrons or really cool science related stuff? If so then please E-Mail me at ryanfordd@yahoo.com

I don't see why not.... If you plan on doing it with aluminum and caustic soda -- be sure to include the appropriate warnings and how to dispose of the by products (needs to go to hazardous waste disposal and not into the garbage or down the drain). It's also very toxic to humans among other things.

aluminum hydroxide looks like a wash away with plenty of water, as it's listed as an irritant in the MSDS (sweep up and flush with water for spills). sodium hydroxide is nutrilize and flush-as a drain cleaner i don't think that you are suposed to fish it out of the drain after you use it : ) if i'm wrong, tell me by how far.

Right for the most part. But the reaction does not stop there.

The first part of the reaction is the sodium hydroxide and the alum oxide layer -- which makes Al(OH)4 (an aluminate)

The second part of the reaction is aluminum + water which makes alum. hydroxide (Al(OH)3).

Then, the alum. hydroxide reacts with the sodium hydroxide (NaOH) to form Al(OH)4 + a lot of heat.

Al(OH)4 is not stable and pretty reactive (depending on what comes in contact with it).

When I've seen people do this (or with lye) it's usually done outdoors. Most of the contents are just dumped into the nearest patch of grass or dirt or down a storm drain. AND, I've never seen anyone wear any form of protection. When mixing with lye, you also get a lye solution in vapor form. Not Fun. The reaction on paper is straight foreword -- but in practice, there's extra variables.

For anyone wondering.... Draino is an aluminum + caustic soda reaction. It's fine in the bottle because it doesn't contain 1 key ingredient.... Water. Once it hits the water -- this reaction starts to get through the clog. There's not much aluminum, so the reaction is somewhat safe when used as directed. AND, municipal water treatment plants know it's coming so they can remove it from the water before discharge :)

i was wondering about the waste mostly. i've made a small H2 generator with Al, water and lye; couldn't get the H2 clean enough or generated fast enough for my taste to take it much farther.
